<h1>m/z distribution histogram</h1>

<h2>Description</h2>

<p>
This module creates m/z distribution histograms of all m/z values in mass lists across specified scans. 
The binning width, in which the m/z values are counted, can be changed dynamically. 
The number of scans that contain a specific m/z value (bin) are plotted.<br>

<h4>Method parameters</h4>
<dl>
<dt>Raw data file, scans filter and mass list</dt>
<dd>Specify the scans and mass lists</dd>

<dt>m/z range</dt>
<dd>Limit the range of the histogram to save performance</dd>

<dt>Retention time range (optional)</dt>
<dd>Limit the scans to a specific retention time range</dd>

<dt>m/z bin width</dt>
<dd>The binning width to count m/z value occurance in scans (can be changed dynamically in the dialog)</dd>

</dl>

<h2>The dialog</h2>

<p>
The "bin width" and "shift bins by" parameter automatically listens for changes and updates the chart (indicated by red/green label above).
Apply a Gaussian fit to a distribution.

<h3>Key bindings</h3>
<p>
Use the arrow keys (left/right) or buttons to jump to the previous or next distribution.
</p>

<h3>Mouse gestures</h3>

<p>
As in most of the other charts, mouse gestures are available to facilitate the chart control. 
<ul>
<li>Use modifier keys (SHIFT/CTRL) and drag the mouse over the axes to zoom, translate and auto zoom the opposite axis </li>
<li>Double click on the plot to jump back in the zoom history (CTRL+double click to jump forward) </li>
<li>Double click on a axis to auto zoom </li>
</ul>
